by Serious Problem with Driveshafts in Mercedes
Sometimes vehicle recalls are related to minor issues, such as a faulty signal for a burnt-out tail light bulb or a missing sticker. However, a new recall from Mercedes concerns a much more serious defect: nearly 25,000 vehicles have a faulty driveshaft that can detach while driving.
Which Models Are Involved in the Recall
The campaign covers 24,092 vehicles from model years 2018 through 2020, including a wide range of E-Class and S-Class models equipped with the 4MATIC all-wheel drive. Among them are the E 400, E 450, S 450, S 560, and even the super-luxury Mercedes-Maybach S 560, as well as corresponding coupes, convertibles, and wagons.
Cause of the Defect and Its Consequences
According to the manufacturer, the problem lies in the driveshaft’s universal joint. Due to incorrect parameters in the supplier’s manufacturing process, the joint can wear out prematurely. If enough lubricant leaks from it, it can crack. This is where the situation turns from inconvenient to truly alarming. Mercedes reports that failure of the joint can disrupt the connection between the transfer case and the front axle. When this happens, the vehicle can suddenly lose drive power without warning.
Mercedes says that owners typically hear unusual noises or feel vibrations before the driveshaft fails. However, after investigating a complaint from outside the USA at the end of 2025, Mercedes discovered that warning signs do not always occur in these cases.
Investigation and Problem Discovery
Engineers spent months trying to understand why one customer reported a loss of drive power without any warning. Additional testing eventually showed that a damaged driveshaft can fail silently, prompting Mercedes to initiate the recall on March 27. The manufacturer reports that it has already received 30 warranty claims in the USA related to this issue, from January 2022 through April 2025, although it does not disclose any accidents or injuries.
Recall Details and Owner Actions
The recall concerns vehicles manufactured from October 1, 2017, through December 18, 2019. Mercedes reports that the supplier’s revised manufacturing process, implemented on December 20, 2019, eliminated the problem. Owners can already check their VIN online to find out if their vehicle is involved. Dealers were notified on April 10, and owners should start receiving recall notifications no later than June 2. Mercedes dealers will inspect the driveshaft and replace it if necessary free of charge.
This situation highlights the importance of proper quality control at all stages of production, especially when it comes to critical safety components like driveshafts. Although the manufacturer has taken steps to correct the process, existing owners face a period of uncertainty and the need to visit service centers. For many, this could be a test of brand loyalty, especially considering Mercedes’ premium status. On the positive side, the company is responding to the problem promptly and covering all costs, which aligns with customer expectations for vehicles of this class.
